Protein phosphorylation modification is crucial for signaling transduction in plant development and environmental adaptation. By precisely phosphorylating components cascades, plants can switch on off the specific pathways needed growth or defense. Here, we have summarized recent findings of key events typical hormone stress responses. More interestingly, distinct patterns proteins result diverse biological functions these proteins.

Molecular Markers and Their Applications in Marker-Assisted Selection (MAS) in Bread Wheat (Triticum aestivum L.)

Agriculture, Journal Year: 2023, Volume and Issue: 13(3), P. 642 - 642

Published: March 8, 2023

As one of the essential cereal crops, wheat provides 20% calories and proteins consumed by humans. Due to population expansion, dietary shift climate change, it is challenging for breeders develop new varieties meeting production requirements. Marker-assisted selection (MAS) has distinct advantages over conventional in plant breeding, such as being time-saving, cost-effective goal-oriented. This review makes attempts give a description different molecular markers: sequence tagged site (STS), simple repeat (SSR), genotyping sequencing (GBS), single nucleotide polymorphism (SNP) arrays, exome capture, Kompetitive Allele Specific PCR (KASP), cleaved amplified polymorphic (CAPS), semi-thermal asymmetric reverse (STARP) target (GBTS). We also summarize some quantitative trait loci (QTL)/genes well their linked markers, which are potentially useful MAS. paper updated information on markers critical traits potential applications breeding programs.

Wheat plant height locus RHT25 encodes a PLATZ transcription factor that interacts with DELLA (RHT1)

Proceedings of the National Academy of Sciences, Journal Year: 2023, Volume and Issue: 120(19)

Published: May 1, 2023

Plant height is an important agronomic trait with a significant impact on grain yield, as demonstrated by the positive effect of REDUCED HEIGHT (RHT) dwarfing alleles (Rht1b) lodging and harvest index in "Green Revolution" wheat varieties. However, these gibberellic acid (GA)-insensitive also reduce coleoptile length, biomass production, yield potential some environments, triggering search for alternative GA-sensitive genes. Here we report identification, validation, characterization gene underlying locus RHT25 wheat. This gene, designated PLATZ-A1 (TraesCS6A02G156600), expressed mainly elongating stem developing spike encodes plant-specific AT-rich sequence- zinc-binding protein (PLATZ). Natural induced loss-of-function mutations plant its overexpression increases height, demonstrating that causative RHT25. RHT1 show genetic interaction their encoded proteins interact each other yeast protoplasts. These results suggest PLATZ1 can modulate DELLA height. We identified four natural truncation one promoter insertion are more frequent modern varieties than landraces, suggesting selection during breeding. be used to fine-tune and, combination genes, replace GA-insensitive Rht1b improvements beyond those Green Revolution

Boosting wheat functional genomics via an indexed EMS mutant library of KN9204

Plant Communications, Journal Year: 2023, Volume and Issue: 4(4), P. 100593 - 100593

A better understanding of wheat functional genomics can improve targeted breeding for agronomic traits and environmental adaptation. However, the lack gene-indexed mutants low transformation efficiency limit in-depth gene studies genetic manipulation breeding. In this study, we created a library KN9204, popular variety in northern China, with reference genome, transcriptome, epigenome different tissues, using ethyl methyl sulfonate (EMS) mutagenesis. This contains vast developmental diversity critical tissues transition stages. Exome capture sequencing 2090 mutant lines KN9204 genome-designed probes revealed that 98.79% coding genes had mutations, each line an average 1383 EMS-type SNPs. We identified new allelic variations crucial trait-related such as Rht-D1, Q, TaTB1, WFZP. tested 100 severe mutations 80 NAC transcription factors (TFs) under drought salinity stress 13 altered sensitivity.

Grain yield improvement by genome editing of TaARF12 that decoupled peduncle and rachis development trajectories via differential regulation of gibberellin signalling in wheat

Published: Aug. 17, 2023

Summary Plant breeding is constrained by trade‐offs among different agronomic traits the pleiotropic nature of many genes. Genes that contribute to two or more favourable with no penalty on yield are rarely reported, especially in wheat. Here, we describe editing a wheat auxin response factor TaARF12 using CRISPR/Cas9 rendered shorter plant height larger spikes. Changes architecture enhanced grain number per spike up 14.7% significantly higher thousand‐grain weight and 11.1% increase under field trials. Weighted Gene Co‐Expression Network Analysis (WGCNA) spatial–temporal transcriptome profiles revealed hub genes: RhtL1 , DELLA domain‐free Rht‐1 paralog, which was up‐regulated peduncle, TaNGR5 an organ size regulator rachis, taarf12 plants.

Published: March 4, 2024

Wheat is an important cereal crop constrained by several biotic and abiotic stresses including drought stress. Understating the effect of stress genetic basis tolerance to develop resilient, high-yielding wheat cultivars. In this study, we investigated effects on seedling characteristics in association panel consisting 198 germplasm lines. Our findings revealed that had a detrimental all under investigation with maximum shoot length (50.94% reduction) minimum germination percentage (7.9% reduction). To gain deeper understanding, conducted genome-wide analysis using 12,511 single nucleotide polymorphisms (SNPs), which led identification 39 marker-trait associations (MTAs). Of these MTAs, 13 were particularly noteworthy as they accounted for >10% phenotypic variance LOD score >5. These high-confidence MTAs further utilized extract 216 candidate gene (CGs) models within 1 Mb regions. Gene annotation functional characterization identified 83 CGs relevance genes encoded WD40 repeat domain, Myb/SANT-like WSD1-like BTB/POZ Protein kinase Cytochrome P450, Leucine-rich domain superfamily, BURP Calmodulin-binding protein60, Ubiquitin-like etc. Findings from study hold significant promise breeders provide direct assistance selecting lines harboring favorable alleles improved tolerance. Additionally, SNPs will enable marker-assisted selection potential genomic regions associated enhanced wheat.
